LUMINARY Russian patent published in 2018 - IPC A01G9/20 A01G7/04 F21V8/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting devices, providing lighting with light, the most appropriate spectrum of sunlight at the expense of use of light-emitting diodes. Luminary contains a set of LEDs with different emission spectra simulating the photosynthetically active part of the solar spectrum equipped with power drivers. Use LEDs whose maximum radiation amplitudes are in the wavelength range 430–650 nm. Spectra of used LEDs overlap each other in different spectral regions of the range, preferably at a level of 0.4–0.6 of the maximum amplitude at the central wavelength of the radiation. Six types of LEDs of different spectrum are used: Warm White, Royal Blue, Blue, Sky Blue, Green and Growing Light, with a possible deviation from the central wavelength at ±15 nm. Drivers of said LEDs are configured to supply power of such a value that the level of the light flux from the corresponding LEDs is equal 0.94; 0.22; 0.57; 0.81; 0.89 from the level of the light flux emitted by the Growing Light LED, with possible deviation of the indicated energy values by ±30 %. Spectrum can be formed by a set of the same type of LEDs with power from 0.1 to 200 W each, with the ability to generate the power of the light flux, the same for each individual type of spectrum. Maximum radiation amplitudes of these LEDs have the maximum radiation at wavelengths, respectively 587, 437, 460, 490, 524 and 650 nm.

EFFECT: invention provides a spectrum of radiation corresponding to sunlight.
